HEAT PUMP HEAT EXCHANGING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heat pump heat exchanging device with excellent heat exchanging efficiency.SOLUTION: The heat pump heat exchanging device comprises a refrigerant circuit 8, and a heat medium circuit 16 that has a water refrigerant heat exchanger 5 and through which a heat medium flows. The water refrigerant heat exchanger 5 is a plate-like heat exchanger. A refrigerant circulating through the refrigerant circuit 8 flows into the water refrigerant heat exchanger 5 from a refrigerant inlet 5a formed on one surface of the water refrigerant heat exchanger 5 and flows out from a refrigerant outlet 5b formed on the same surface as the surface on which the refrigerant inlet 5a is formed. The heat medium flowing in the heat medium circuit 16 flows into the water refrigerant heat exchanger 5 from a heat medium inlet 5c formed on one surface of the water refrigerant heat exchanger 5 and flows out from a heat medium outlet 5d formed on a surface opposite to one surface. Distribution of a flow rate of the heat medium flowing inside the water refrigerant heat exchanger 5 becomes uniform, and heat is efficiently exchanged inside the entire water refrigerant heat exchanger 5, so as to improve heat exchanging efficiency.
